Abstract

Alpha satellite DNA is composed of variants of a short consensus sequence that are repeated in tandem arrays in the centromeric heterochromatin of each human chromosome. To define centromeric markers for linkage studies, we screened human genomic DNA for restriction fragment length polymorphisms using a probe detecting alphoid sequences on chromosomes 13 and 21. We describe one such DNA polymorphism. Analysis of linkage of this DNA marker to other polymorphic markers in the CEPH pedigrees demonstrates linkage to markers on the proximal long arm of chromosome 13 and defines the centromeric end of the linkage map of this chromosome.
